It is time for SDS to admit that having the prestige grinds be online only was a big mistake and move them to any mode (ie offline included) within the next update or two. The prestige grind has completely ruined events with a huge swath of people playing just for prestige (ie hitting and quitting, pitching and quitting, or just outright asking for stats), which has taken the fun out of events and made them into nothing more than grinding opportunities.
The idea that it takes more skill and/or time to prestige a card online went out the window as soon as these cards were included in events and thus allowing people who prefer to play offline wouldn’t change any dynamic in the prestige process other than to clean up events AND likely make a ton of their customers very happy.
Forcing people to play online to prestige cards didn’t work and it’s past time to rectify this mistake and move all these grinds to any mode.
